LGU1C123MELZ

The LGU1C123MELZ is a snap‑in terminal aluminum electrolytic capacitor offering 12,000 µF (12 mF) capacitance at a 16 V rating in a radial, can‑type snap‑in package. Engineered for general‑purpose applications, it delivers high capacitance density with specified ripple current handling and long endurance for demanding thermal environments.

Key value comes from its 105°C endurance rating (3000 hours), measurable ripple current capabilities at both low and high frequencies, and a compact φ22 × 35 mm form factor optimized for rack or chassis power assemblies and other industrial and electronic systems that require bulk energy storage and smoothing.

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance at a rated voltage of 16 V with ±20% tolerance (120 Hz, 20°C).
• Snap‑In Radial Package — Snap‑in terminal, radial can package (φ22 × 35 mm) designed for secure board mounting and mechanical stability.
• High Temperature Endurance — Rated for operation from −40°C to +105°C with a specified endurance of 3000 hours at 105°C under rated ripple and DC bias conditions.
• Ripple Current Capability — Supports 2.31 A at 120 Hz (low frequency) and 2.656 A at 50 kHz (high frequency), with frequency coefficients provided for system design.
• Leakage and Dissipation — Specified leakage current (approximately 1310 µA) and tan δ up to 0.50 at 120 Hz for the 16 V rating, enabling predictable loss budgeting.
• Regulatory Compliance — RoHS‑compliant construction.
• Production & Packaging — Tray packing and mass production status suitable for volume assembly workflows.

Typical Applications

• General‑Purpose Power Modules — Bulk capacitance for smoothing and energy storage in general‑purpose power assemblies where high capacitance and 105°C endurance are required.
• Power Supply Filtering — AC ripple reduction and DC filtering in supplies that benefit from high ripple current capability at both low and high frequency.
• Industrial Electronics — Use in industrial control and power electronics that require robust temperature performance (−40°C to +105°C) and prolonged operating life.

Unique Advantages

• High Bulk Energy Density: 12,000 µF nominal capacitance at 16 V provides substantial energy storage in a compact φ22 × 35 mm can.
• Designed for Elevated Temperatures: 3000‑hour endurance at 105°C supports long‑term operation in high‑temperature environments.
• Predictable Ripple Performance: Specified ripple currents at 120 Hz and 50 kHz let designers size cooling and filtering reliably across frequencies.
• Secure Board Mounting: Snap‑in radial can termination simplifies mechanical retention in heavy‑vibration or high‑current board layouts.
• Measured Electrical Characteristics: Defined leakage current and tan δ values aid in power‑loss and thermal management calculations.
• RoHS Compliance and Production Ready: Environmentally compliant construction with tray packing for volume manufacturing.
